A model for calculating the dissociative ionization cross sections of diatomic molecules is developed. The activated state for dissociative ionizations is modeled to occur via the ejection of a bound electron and an excitation of another bound electron. This process is described by successive two-electron scattering in the first Born and the binary-encounter approximations. Comparison of calculated cross sections with available experimental data for five diatomic molecules (H$sub 2$, CO, N$sub 2$, NO, and O$sub 2$) shows good agreement with incident-electron energies above 200 eV.
